Building an AI-Powered EEG Analysis System for Mental State Classification
Introduction Electroencephalography (EEG) has become an essential tool in neuroscience and mental health research, offering insights into brain activity patterns. This project focuses on developing an AI-driven EEG classification system capable of identifying mental states such as Calm, Neutral, and Stressed . By leveraging machine learning, deep learning, and API integration , the system enables efficient and scalable EEG data analysis. This blog post outlines the entire AI pipeline , including data preprocessing, feature extraction, model selection, evaluation, and API deployment for real-time interaction. 1. Dataset & Preprocessing Data Sources The system processes EEG datasets stored in CSV format , each containing raw time-series EEG signals from multiple electrode channels. These datasets are collected from various individuals under different cognitive conditions. Preprocessing Pipeline Given the complexity and noise inherent in EEG data, robust preprocessin...
